Single electron transfer photoinduced oxidation of piperidine and pyrrolidine derivatives to the corresponding lactams
Abstract
Irradiation by visible light of various N-arylaminopiperidines or N-arylaminopyrrolidines in presence of a catalytic amount of photosensitizer led with good yields to the corresponding N-arylaminolactams under mild conditions. This reaction proceeds by two consecutive photooxidations, the first in presence of
